The utility model relates to a case modified line cable magnetic field manifold type electrified indicating ware, including getting electric metal response piece and indicator body, get electric metal response piece cladding formation electromagnetic induction on the case becomes the cable insulation surface and connect, to get electric metal response piece and be connected with the signal input part electricity of indicator body, the indicator body includes protection circuit, charging circuit, switch circuit and luminous component. The utility model discloses utilize the electrostatic field of high tension cable production itself, cladding foil on the outer wall of half conductive rubber cover, response principle according to electric capacity, can produce induced charge on foil, it is leading -in to the circuit in the electric charge, charge to electric capacity, when the charge integration produces certain voltage to the certain degree, automatic the opening of switch portion spare at electric capacity both ends is discharged, light the luminous component in the return circuit of discharging, judge in view of the above whether electrified the cable is, thereby improved case modified line cable and tested the fail safe nature that the electrician did, therefore, the clothes hanger is strong in practicability, and has high economic value.
